Gold Mining Operation 10 - 30 years. The gold mining operation stage represents the productive life of a mine, during which ore is extracted and processed into gold. Processing involves transforming rock and ore into a metallic alloy of substantial purity – known as dor – typically containing between 60-90 gold.
The plant production is how much are the raw rock is mined and processed to extract the gold. Gold is expressed in troy ounces. Gold Recovery And once gold is extracted through the plant at the gold grade, the gold gets further processed to become refined. To get the refined simply multiply the recovery rate to the gold produced. Operating Costs.
